15 1/3 * 12=184 because 15 *12 *1/3
Answer:
x = 128 degrees
Step-by-step explanation:
First figure out the angle inside the triangle
1st step: add 55 and 73 together:
⇒ 55 + 73 = 128
2nd step: subtract the sum from 180:
⇒ 180 - 128 = 52
to find x, take 180 again and then subtract 52 from it:
⇒ 180 - 52 = 128
